It’s only a five rounder, but it would seem other people are getting the idea. In our project to make a 30 round magazine for an M11 submachine gun, we found that the ABS plastic the Makerbot uses to be a bit too flexible for a 30 round magazine. At some point, Jason and I will get around to test firing the design we worked on. But this is pretty neat, considering this 5 round AR mag uses a plastic spring also made on the 3D printer. Our magazine used a metal spring that was from a broken magazine.

You gotta wonder if the last factory on earth won’t close up for good within ten years as we all just change over to downloading the programs to print whatever object it is we want on our home-model 3D printer. That is about the coolest thing ever!

That’s really neat. Technology changes everything and it’s all moving at such a fast pace. It’s only a matter of time before manufacturing changes forever. One day we might be able to print our own working firearms.
